Evaporation of sessile droplets containing non-volatile solutes dispersed in a volatile solvent
leaves behind ring-like solid stains. As the volatile species evaporates, pinning of the …

Coffee-ring effect is an omnipresent phenomenon, it features the circular deposition on the
surface after the evaporation of a droplet containing particles. Ever since the seminal report …

The marriage of highly sensitive biosensor designs with the versatility in sample handling
and fluidic manipulation offered by lab-on-a-chip systems promises to yield powerful tools …

In the evaporation of microlitre liquid droplets, the accepted view is that surface tension
dominates and the effect of gravity is negligible. We report, through the first use of rotating …

Sessile droplets are non-movable droplets spanning volumes in the nL-to-μL range. The
sessile-droplet-based platform provides a paradigm shift from the conventional, flow-based …

It has been 14 years since the inaugural microfluidics review in Analytical Chemistry was
published. 1 The first papers describing these devices which are also commonly referred to …

The coffee-ring effect denotes the accumulation of particles at the edge of an evaporating
sessile drop pinned on a substrate. Because it can be detected by simple visual inspection …

The evaporation of a drop of colloidal suspension pinned on a substrate usually results in a
ring of particles accumulated at the periphery of the initial drop. Intense research has been …

This study presents the spreading of a single filament of a yield stress (viscoplastic) fluid
extruded onto a pre-wetted solid surface. The filaments spread laterally under surface …

The microtiter plate has been an essential tool for diagnostics, high-throughput screening,
and biological assays. We present an alternative platform to perform bioassays in a …
